Highway Performance Monitoring System
The Highway Performance Monitoring System (HPMS) is a nationwide FHWA inventory system that includes data for all of the Nation's public road mileage as certified by the States' Governors on an annual basis. It provides data that reflects the extent, condition, performance, use, and operating characteristics of Tennessee's highways. HPMS calculates the Vehicle Miles Traveled (VMT), which is equal to the Average Annual Daily Traffic (AADT) multiplied by the total miles of the system.
VMT reports include:
- VMT by Administrative System gives the Total Vehicle Miles Traveled as calculated by the Administrative Systems mileage multiplied by the AADT of each Administrative System.
- VMT by Functional Classification gives the Total Vehicle Miles Traveled as calculated by the Functional Systems mileage multiplied by the AADT of each Functional Classification.
- VMT by County gives the Total Vehicle Miles Traveled as broken out by county functional class mileages multiplied by the county AADT.
